Claims. 1

This invention pertains to improvements in attic access dormer vents for use in connection with roof structures of buildings.

One of the objects of this invention is to provide an improved attic access dormer vent which provides for adequate ventilation below a diagonal roof surface while at the same time providing an access opening to get into the attic area below the roof for purposes of examination, adjustment of equipment and the like.

Another object of this invention is to provide an improved combined attic ventilator and access cover arrangement which is self-contained and may be opened under adverse weather conditions such as high winds and which may be secured in place to accommodate itself to any type of severity of weather.

Still further object of this invention is to provide an attic access dormer vent for a sloping roof which is hingedly mounted to the frame structure of the vent in such a manner that it may be readily manipulated with one hand for opening and closing while providing weather protection under all conditions and a ventilating area in the vent structure for the under roof area of the building.

Further features and advantages of this invention will appear from a detailed description of the drawings in which:

Fig. 1 is an outside perspective view of the attic access dormer vent incorporating the features of this invention.

Fig. 2 is a section on the line 2-2 of Fig. 1.

Fig. 3 is an enlarged perspective view of one of the hinges.

Fig. 4 is a section on the line 4t of Fig. 1 showing the locking device for holding the vent in closed position.

For exemplary purposes this invention is shown applied to an attic access dormer vent customarily used in connection with slanting roof structures such as the roof Ill having the usual roofing material H such as slate, tile, tar paper or the like. Fixed to the sheeting boards l2 carried by the roof rafters I3 is the base frame or jack section It comprising the portions l5, l6, H, and I8 appropriately secured together to form the rectangular or square frame. An upturned lip or baffle section i9 is provided around the inner opening of the frame it and coincides with the opening provided in the sheeting boards 12 of the roof. The frame structure i4 is securely nailed or screwed to the sheeting boards 82 in any suitable manner.

An access cover is provided with a louvered front face 2| having a series of louver blades 22 and a screen 23 fixed to the inside of the louvered opening. Extending backwardly from the front 2| are the side portions 24 and 25 which terminate in the top cover portion 26 to form a com-- plete unitary structure. The top surface 2% preferably extends back substantially horizontally to engage the side portions 24 and 25 in the edge 27, which edge in turn is connected thru suitable hinges 28 and 29 to the frame member it of the frame l4 fixed to the roof as descirbed. Thus the cover may be swung from the closed position 20a, Fig. 2, to the opened position 2%, Fig. 2, so that entrance may be gained through the frame I4 to the interior portion under the roof I0. I

When the cover 20 is swung forward to closed position a clamping screw 21a carried in the lower of the louvers 22 is adapted toengage in an opening 29 in the strip 30 secured to the member I8 of the frame [4 fixed to the roof of the building structure. Thus in this way the cover is securely held in position on the roof against any adverse weather conditions. It is also to be noted that it folds back by means of the hinges 28 and 29 to the positions 2%, Fig. 2, so as to in no way obstruct access through the opening in the member l4 and at the same time can not be dislodged by high wind velocity when in opened position.

While the apparatus herein disclosed and described constitutes a preferred form of the invention, it is also to be understood that the apparatus is capable of mechanical alteration without departing from the spirit of the invention and that such mechanical arrangement and commercial adaptation as fall within the scope of the appendant claims are intended to be included herein.

Having thus fully set forth and described this invention, what is claimed as new and desired to be secured by United States Letters Patent is:

1. An attic access dormer vent comprising, a flat plate base frame fixed to the roof having an opening coinciding with an opening through said roof, an upturned lip formed around the edge of said opening in said base frame, a dormer vent cover comprising a vertically disposed louver opening facing down slope of the roof, a series of louvers in said vertically disposed louver opening, screen means behind said louvers fixed to said cover, a substantially horizontally disposed top surface on said cover terminating in vertically disposed side portions, and hinge means mounted on the top surface of said base frame connecting the rear edge of said top surface to said frame so that said cover may be swung from a closed position over said frame to an open position up slope of said roof to provide an access and ventilating opening for the roof structure.

2. An attic access dormer vent comprising, a flat plate frame member fixed to the roof having an opening coinciding with an access opening in said roof of a building, an upturned lip formed around the edge of said opening in said frame membena dormer :shaped vent :cover hingedly connected at its upper rear edge to the top upper surface of said frame, a vertically disposed louver opening in thedown slope face of said dormer, a plurality of louvers fixed .in saiclopening, screen means behind said louvers, said dormer shaped vent cover comprising asubstantially horizontal top portion terminating in vertically disposed side portions interconnecting the rear portion of said cover with said louvered front face.

3. An attic access dormer vent comprising, a frame member fixed'to the roof :having ;anopening coinciding with an .access opening in said roof of a building, an upturned lip formed around the edge of said opening in said frame member, a dormer shaped vent-cover :hingedly connected at its upper rear edge of the top upper surface of said frame, a verticallydisposed louver opening in the down slopeface .of said dormer, a plurality of louvers fixed inosaid opening, screen means behind said louvers, said dormershaped vent cover comprising a substantially horizontal top portion terminating in vertically disposed side portions interconnecting the .rear portionof: said cover with said louvered'frontiface, and locking means interconnectable between the lower louver of said front face and said frame to .securesaid cover in closed position over :saidaccess opening of said frame.

4. A dormer vent closure for anaccess opening in a sloping roof structure comprising, a flat plate framehaving a central .opening mating the access opening in said :roof, .an upturned lip formed around the edge of said centralopening in said flat plate frame, a dormer shaped cover for said opening including hinges for securing the upper rear-edge of .saiddormer shaped cover to the top upper surface of 'said;frame so that said cover may be swung upwardly and backwardly on the up slope portion of the roof above said access opening, a substantially horizontally disposed top surface on said cover terminatin in substantially vertically disposed side surfaces thereof, a ventilating opening in the front down slope facing surface of said dormer shaped cover, a plurality of louvers in said ventilating opening, screen means disposed behind said louvers, said upturned lip extending upwardly inside of said cover to provide a water tight weather proof structure for said roof.

5. A dormer vent closure for an access opening in aslopingroof structure comprising, a fiat plate frame having a central opening aligned with the access opening in said roof, an upturned lip formed around the edge of said central opening in said frame, a dormer shaped cover for said opening including hinges for securing the upper rear edge of said dormer shaped cover to the top upper surface of said frame so thatsaid cover maybe swung upwardly and backwardly on the up slope portion of the roof above said access opening,,a substantially horizontally disposed top surface on said cover terminating in substantially vertically disposed side surfaces thereof, a ventilating opening in the front down slope facing surface of said dormer shaped cover, a plurality of louvers in said ventilating opening, screen means disposed behind said louvers, said upturned .lip extending upwardly inside of said cover to provide a water tight weather proof structure for said :roof, and locking means intel-connected between the lower louver of said louvered-portion of said'cover and the top surface of said frame for securing said cover in closed position on said frame.
